Begging is an activity that involves the submissive being forced to kneel and beg the dominant.

This begging can often be for something that the submissive wants to do, such as being able to worship the dominant's feet or legs, or it could be a case of the submissive being forced to beg for punishment, such as a spanking.

Generally begging is considered to be a humiliating act, and the fact that the submissive begs from a kneeling position emphasises this.
